9.3: Nomenclature and Ligands - Chemistry LibreTexts
In neutral and cationic complexes the metal's name is used directly. - e.g. as in hexammine ruthenium (III) for [Ru (NH 3) 6] 3+. In anionic complexes, - ate replaces - ium, - en, or – ese or adds to the metal name, e.g., as in hexachloromanganate (IV) for MnCl 62-.
Ethylenediamine - Wikipedia
Ethylenediamine is a well-known bidentate chelating ligand for coordination compounds, with the two nitrogen atoms donating their lone pairs of electrons when ethylenediamine acts as a ligand. It is often abbreviated "en" in inorganic chemistry.
What is the meaning of ' (en)'? - Chemistry Stack Exchange
The en ligand is an example of a multidentate (or chelate) ligand which may form more than one coordinating bond per molecule, while the $\ce{NO2^-}$ and $\ce{CN-}$ are monodentate ligands.
Ligands - Chemistry LibreTexts
2023年6月30日 · Ligands are ions or neutral molecules that bond to a central metal atom or ion. Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid (electron pair acceptor). ….
19.2 Coordination Chemistry of Transition Metals - OpenStax
In the complex [Co(en) 3] 3+, there are three bidentate en ligands, and the coordination number of the cobalt(III) ion is six. The most common coordination numbers are two, four, and six, but examples of all coordination numbers from 1 to 15 are known.

Coordination Complexes and Ligands - Division of Chemical …
Ethylenediamine (en) is a typical bidentate ligand. Each end of this molecule contains a pair of nonbonding electrons that can form a covalent bond to a metal ion. Ethylenediamine is also an example of a chelating ligand .
5.2: Ligands and Nomenclature - Chemistry LibreTexts
Coordination Complexes are named as the ligand derivatives of a metal. Rule 1: If ions are present, name the cation first, followed by the anion. Rule 2: When multiple isomers are possible, designate the particular isomer in italics at the front of the name of each complex.
Ligand - Wikipedia
In coordination chemistry, a ligand[a] is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. [1] .
Ligands: Definition, Types, and Examples - Chemistry Learner
A ligand is a molecule or ion that can donate a pair of electrons to a central metal atom or ion. The donated electron pair forms coordinate bonds with the metal, forming coordination compounds. Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid (electron pair acceptor).
